<h1>xrh</h1>
<h4>Usage</h4>
<pre>
<i>mystateEngine.xrh(eventName, val, target)</i>
</pre>
<h4>Parameters</h4>
<p><i>eventName</i> Name (string) of request</p>
<p><i>val</i> Value associated with the request</p>
<p><i>target</i> (optional) The instance generating the request</p>
<h4>Returns</h4>
<p>Since this method is supposed to be overriden if it is used, by default, it returns <code>undefined</code></p>
<h4>Description</h4>
<p>This is the default external request handler for the state engine. Developers must override this method if they expect to receive requests from outside objects (outside objects explicitly call this method). The default method merely announces that it has been called, and returns <code>undefined</code>.</p>
